Figure 2
Images of the direct beam after the collimating 2D multilayer X-ray optics and ∼180 cm beam path. (a) Cross section of the full beam, (b) the beam with narrower slit settings, and (c) the beam after the multilayer mirror and Ge(111) channel-cut monochromator. The FWHMs in the X and Z directions are estimated with 1D Gaussian fits to the intensity data (the dashed black line is the Gaussian fit and the red line is a plot of the intensity value at that pixel).
